The Agnus Dei, “Lamb of God,” represents Christ in the form of a lamb. The image is based on the words of John the Baptist in the Gospel of John: “Behold, the Lamb of God.” It also draws on biblical sacrificial language and Revelation, where the Lamb takes on a victorious and celestial significance. In Christian art, the animal may be lying down, carrying a cross or banner, and pouring its blood into a chalice.

Why is Jesus called the Lamb of God?
In the Gospel of John, John the Baptist identifies Jesus as “the Lamb of God who takes away the sin of the world.” This formula provides the direct basis for the symbol.
The animal therefore does not simply represent gentleness and innocence. It refers to a precise Christological identity and sacrificial language.
The Metropolitan Museum presents Zurbarán’s Agnus Dei as an image in which the bound lamb intended for sacrifice represents Christ’s body.
What is the connection with the paschal lamb?
Christianity interprets Christ’s death in light of the paschal lamb and biblical sacrifices. The lamb thus becomes an image of an offered sacrifice.
This connection explains compositions in which the animal carries a cross or pours its blood into a chalice. The image associates the Passion with the Eucharist.
The symbol therefore goes beyond an idea of purity. It brings together death, offering, and salvation in an easily identifiable animal figure.
Why is the Lamb also victorious?
In Revelation, the Lamb appears alive after being sacrificed. He opens the seals and receives honor and power.
This vision transforms the sacrificed animal into a figure of victory. A banner may accompany the Lamb to make the Resurrection and triumph over death visible.
The Phoenix also expresses resurrection in Christian art, but through an animal narrative inherited from Antiquity. The Agnus Dei has a directly scriptural foundation.
How can the Agnus Dei be recognized?
The lamb may be lying down with its legs bound, standing with a cross, or carrying a banner. A cruciform halo indicates its Christological nature.
On a 12th-century Spanish crucifix preserved at the Met, the Lamb of God appears on the reverse, surrounded by the symbols of the Evangelists.
The image therefore varies greatly depending on the context: silent sacrifice in a painting, a victorious emblem on a banner, or the focus of a liturgical composition.
Why does the formula remain central to the Mass?
“Agnus Dei” also refers to a prayer in the Latin liturgy, sung or recited during Mass. The formula asks Christ, the Lamb of God, for mercy and peace.
The visual symbol and the liturgical text reinforce each other. An image of the Lamb immediately recalls a familiar formula from the celebration.
This continuity explains the emblem’s longevity: it survives not only in museums, but also in a still-living religious language.
